“There is no enthusiasm among Republicans for Carl Paladino,” said Siena pollster Steven Greenberg.

“The governor’s race is not attracting Republicans to come out and vote,” he continued.

Marist College polling director Lee Miringoff said, “Paladino doesn’t appear to be the kind of candidate to generate the enthusiasm and presence at the top of the ticket to get people starting out voting on the Republican line.

“And to the extent that people vote a straight ticket, you may have people starting out on the Democratic line — because of Paladino — who might otherwise have been on the Republican line,” he continued.

Many top state Republicans say privately that Paladino’s intemperate and bellicose outbursts, anti-gay ravings, forwarding of racist and pornographic e-mails, and wild unsubstantiated charges against Cuomo and others have damaged all GOP candidates.

In response, many Republican contenders — including Donovan and Wilson — have refused to endorse Paladino.

Meanwhile, the new poll showed incumbent Democratic Sens. Chuck Schumer and Kirsten Gillibrand with massive leads over their GOP opponents, with Schumer ahead of political consultant Jay Townsend, 67 percent to 28 percent, and Gillibrand ahead of former Rep. Joseph DioGuardi, 60 percent to 31 percent.
